1附着装置的可靠性判定塔机附着装置可靠与否直接关系到塔机的安全。附着装置是否可靠可根据以下两个原则判定。原则一:附着体系必须是几何不变体系,即在不考虑弹性变形的条件下,体系的几何形状和位置是不可改变的。因此附着杆系的布置必须含有三角形单元,只有三角形可以保持几何形状不变。原则二:附着框、附着杆、附墙座以及固定附墙座的建筑结构必须有足够的强度,在外力作用下不发生破坏。
1, the reliability of the attachment to determine whether the reliability of the tower crane attached to the tower crane is directly related to the safety. Whether the attachment is reliable or not can be judged according to the following two principles. Principle one: The attachment system must be a geometric invariant system, that is, without considering the elastic deformation conditions, the system geometry and location can not be changed. Therefore, the attachment of the rod system must contain triangular cells, only the triangle can maintain the same geometry. Principle two: attached to the box, attached to the pole, with the wall base and the wall with a fixed building structure must have sufficient strength, under the action of external force does not occur damage.
